In the latter Table we see the same indication of a tendency to increase of mor- 

 tality with increase of rainfall, the exceptional months being, as in the case of the 

 number of rainy days, March, July, August, September, and November, but in this 

 case April also slightly opposes the general indication. It is observable that, in 

 both instances, whether with an excess or deficit of the rainfall, the mortality is 

 below that of the average of the six corresponding months taken over the whole 

 year. Now, if instead of being content with the indications as given by a com- 

 parison of the month of absolute highest with the month of absolute lowest rain- 

 fall, we compare all the months which have a rainfall above the average rainfall 

 of each group of corresponding months, with all the months which have a rain- 

 fall below the mean of the six corresponding months, we obtain the following 

 result : — 





Average Mortality of those 



Average Mortality of those 





Months which have a Rainfall 



Months which have a Rainfall 





greater than the Mean of the 



less than the Mean of the 





Six corresponding Months.
